Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

(phase I):

  • Patient indicated for cardiac pacing according to the most recent guidelines from the European Society of Cardiology (ESC)
  • Patient planned for a de novo implantation of any Single Chamber (SR) or Dual Chamber (DR) CE marked pacemaker
  • Patient planned for a catheter-guided implantation in the interventricular septum area
  • Patient planned for the implantation of any CE marked ventricular pacing lead compatible with the FLEXIGO delivery catheter
  • Patient reviewed, signed and dated the Informed Consent Form (ICF)

Inclusion criteria

(phase II):

  • Patient indicated for cardiac pacing or CRT according to the most recent guidelines from the ESC
  • Patient planned for a de novo implantation of any SR or DR CE marked pacemaker, or any CE marked CRT-D
  • Patient planned for a catheter-guided implantation in the interventricular septum area
  • Patient planned for the implantation of any CE marked ventricular pacing lead compatible with the FLEXIGO delivery catheter
  • Patient reviewed, signed and dated the ICF

Exclusion criteria

(phase I):

  • Patient planned for a device upgrade, or a device or a lead replacement
  • Patient with a congenital heart disease
  • Patient with significant hypertrophic cardiomyopathy, cardiac amyloidosis or obstructive hypertrophic cardiomyopathy
  • Patient with a Left Ventricular Ejection Fraction (LVEF) ≤ 35%
  • Patient already enrolled in another clinical investigation that could confound the results of this clinical investigation (e.g., clinical investigations involving intra-cardiac device)
  • Patient implanted despite a contraindication for cardiac pacing system implantation (i.e. patient implanted with a defibrillator, patient contraindicated for a single dose of 310 μg of dexamethasone sodium phosphate, patient implanted with a tricuspid replacement heart valve, with prior tricuspid valve intervention or with a significant tricuspid valve disease that may lead to future replacement heart valve surgery)
  • Minor age patient (i.e. under 18 years of age)
  • Incapacitated patient, under guardianship, kept in detention, refusing to cooperate or not able to understand the purpose of this clinical investigation
  • Non-menopausal women

Treatment and study plan

Use of FLEXIGO delivery catheter

Device

Use of FLEXIGO delivery catheter for implantation of ventricular pacing lead

Primary outcomes

  1. Absence of Unanticipated Serious Adverse Device Effect (USADE) related to FLEXIGO delivery catheter

    Time frame: 72 hours after implantation

    Any event caused by use of the FLEXIGO delivery catheter or any accessory packaged with the catheter, will be considered as an ADE related to the FLEXIGO delivery catheter. The primary endpoint evaluation will be based on Sponsor assessment of safety events, based on investigational site reporting.

Secondary outcomes

  1. Implantation success rates

    Time frame: During implantation

    • Implantation success rate with FLEXIGO delivery catheter: Proportion of lead successfully implanted at the interventricular septum with use of the FLEXIGO delivery catheter.
    • Left Bundle Branch Area Pacing (LBBAP) implantation success rate with FLEXIGO delivery catheter: Proportion of lead successfully implanted at the interventricular septum with use of the FLEXIGO delivery catheter and fulfilling LBBAP success criteria according to the operator's decision.
    • LBBAP implantation success rate (overall): Proportion of lead successfully implanted at the interventricular septum with use of any material and fulfilling LBBAP success criteria.
  2. Implantation time

    Time frame: During implantation

    Total procedural time and total fluoroscopic time documented per type of cardiac device implanted and per model of catheter used.

  3. Implantation usability

    Time frame: During implantation

    Implantation usability of the FLEXIGO delivery catheter documented through handling scores based on a specific questionnaire addressed to the operator after implantation.

  4. Serious Adverse Device Effect (SADE) rate related to FLEXIGO delivery catheter or the slitter

    Time frame: 72 hours after implantation

    Proportion of SADE related to the FLEXIGO delivery catheter or the slitter.

  5. Left Bundle Branch Area Pacing (LBBAP) implantation success rate per indication (cardiac pacing and CRT) and per ventricular pacing lead model

    Time frame: During implantation

    • LBBAP implantation success rate with FLEXIGO delivery catheter (documented in cardiac pacing and CRT-D populations separately): Proportion of lead successfully implanted at the interventricular septum with use of the FLEXIGO delivery catheter and fulfilling LBBAP success criteria according to the operator's decision.
    • LBBAP implantation success rate (overall, and documented in cardiac pacing and CRT-D populations separately): Proportion of lead successfully implanted at the interventricular septum with use of any material and fulfilling LBBAP success criteria according to the operator's decision.
